Given:
Distance Travelled = 100 metres
Time Taken = 50 seconds
To Find:
The speed of the cyclist in km/hr.
Formulas Used:
- Speed = Distance / Time
- m/s × 18/5 = km/hr
Explanation:
Speed (in m/s) = 100 metres / 50 seconds
Speed (in m/s) = 2 m/s
By converting it into km/hr, we get
2 m/s × 18/5 = 36/5 km/hr = 7.2 km/hr
Answer:
The speed of the cyclist is 7.2 km/hr.
SristiChauhan:
but from where u have taken 18/5.
that's the formula of changing m/s into km/hr
same goes to the other process, I mean ...to change km/h into m/s , we multiply the km/h with 5/18
but how I'm not able to understand
to change km/h into m/s , we multiply 5/18 to km/h
ohhh thanks
so when changing m/s into km/h, we multiply 18/5 ( it's reciprocal ) to m/s

hope you understood! ^^
